Features
Rotary Self-Cleaning Screen
The enclosed engine compartment and rotary self-cleaning screen protect the engine from dirt and debris buildup. An enclosed engine compartment also reduces the noise level. The 1155 also gives you easy access to the engine with a 3-door entry on either side, plus a front door to the radiator.
C15 Caterpillar Electronic Diesel Engine
Powered by either a 475 HP (354 kw) or a 540 HP (403 kw) C15 Caterpillar Electronic diesel engine with state-of-the-art electronic fuel injection system, fuel consumption is decreased. This allows it to produce ground hay at a rate that will make you money on every job. It’s strong enough to chew through those tough, wet bales, and it has all the features you’ve come to expect from Caterpillar, including reliability, cold weather starting, unsurpassed product support, and proven resale value.
KPTO Fluid Coupler
The KPTO fluid coupler transmits power with up to 98% efficiency and eliminates the mechanical clutch. It’s goof-proof. Acting as a torque limiter, it can engage or disengage at full engine RPM without damage – reducing the chance of problems in the drive train.
50 Degree Oscillating Stacking Conveyor
The 30 in. wide x 26 ft. long stacking conveyor piles hay to over 18 feet in height. The conveyor can oscillate left to right up to 50 degrees, which means you can not only make the pile tall, you can make it wide as well.
50” Big Bite Hammermill
The Big Bite hammermill is located at the rear of the tub frame, reducing the length of the belly conveyor, improving the belly conveyor service accessibility, and moving the dust away from the operator. The hammermill is also dynamically balanced to give you smoother operation, longer life, and less maintenance.
90 Degree Tub Tilt
The 11 ft. wide x 50 in. deep tilt tub opens a full 90 degrees for access to the hammermill and screens as well as for normal servicing.
11’ Tub with Tip in Tub Flares (Sides)
The 11 ft. wide x 50 in. deep tub has tip in tub flares (sides). The sides are folded in to narrow the transport width of the grinder.
Command Console with Optional Remote Control
A central command console is conveniently located and controls all the functions of the machine. An optional remote control is available to keep you out of the dust. It controls the tub rotation, conveyor lift, conveyor articulation, and engine stop. The electronic governor keeps the engine RPMs constant, resulting in increased efficiencies and constant load.

Standard Features
- The Truck Mounted Big Bite 1150 is easy to transport between jobs and is easy to maneuver into tight spots. Because the unit is mounted over the truck's rear axles, there is traction to get through the sloppiest farm and hay yards.
- The exclusive, innovative self-cleaning rotary screen protects the radiator and engine air intake from chaff and fines. That means no more plugged radiators, so there’s less down time.
- The KPT Fluid coupler transmits power with up to 98% efficiency and eliminates the mechanical clutch. It’s goof proof, can engage or disengage at full engine RPM without damage, and requires minimal maintenance.
- The 30 inch x 26 ft. discharge conveyor piles hay over 18 feet high. The conveyor can articulate left to right up to 50 degrees which means you can not only make the pile big, you can make it wide too.
